Description:

When trying to upload a sketch using "SparkFun ESP32 Thing Plus" as the board in the Arduino IDE I get the following error message:

Sketch uses 760949 bytes (11%) of program storage space. Maximum is 6553600 bytes.
Global variables use 34604 bytes (10%) of dynamic memory, leaving 293076 bytes for local variables. Maximum is 327680 bytes.

Using "Adafruit ESP32 Feather" as stated in the ESP32 Thing Plus Hookup Guide by Sparkfun (it was done before #4224) works without an issue:

Sketch uses 760949 bytes (58%) of program storage space. Maximum is 1310720 bytes.
Global variables use 34604 bytes (10%) of dynamic memory, leaving 293076 bytes for local variables. Maximum is 327680 bytes.

esptool.py v3.1

Connecting......

Comparing both commands I would guess that {upload.flags} shouldn't be there.

Also there is a huge difference in program storage space between both boards (6553600 vs 1310720 bytes), is this correct? It seems odd to me considering that the manufacturer appears to consider them equivalent.

Thank you.

I just tried to upload the sketch after updating to RC2 and the issue is still present.

@riosnav Update the boards.txt file to add:

esp32thing_plus.upload.flags=

Which appears to have been missed for this board, possibly others.

This did the trick! Thank you.
